can i handle my baby mice?

  I have baby mice that are 1 wk old,, im a bit weary of handling them just yet as ma mouse ate quite a few when she gave birth. I dont even know how many she has as i have not even disturbed her nest as i want all the other babies to be safe.

Ive checked on-line but theres so many different answers im just not sure??

please help
My grandmother had baby mice and she says she handled hers.
